Flight Management System (FMS) for the Agusta AW139/AB139 Helicopter
Intercept Using Heading Select
The heading select intercept consists of flying a heading out of the first
waypoint until intercepting a radial or course into a second waypoint.
The intercept point is not defined as a latitude/longitude since any
heading is flown out of the first waypoint. When flying outbound from
the first waypoint, the FMS monitors the capture criteria for the radial
or course inbound to the second waypoint. When lateral navigation
(LNAV) is armed, the FMS captures the inbound course to the second
waypoint when the capture criteria is satisfied. Procedure 9--4 gives an
example.
